How to measure 4/9 cup
- With standard cups & spoons: 1/3 cup + 1 tbsp + 2 tsp + 1/4 tsp + 1/8 tsp — rounded to the nearest measurable spoon — level it off slightly generously.
- By volume: 105 ml, or 3.56 fluid ounces — handy if you have a measuring jug.
- By weight (most accurate): see the gram table below for common ingredients.
Here's the math: 1⅓ cups is 21⅓ tablespoons. Take a third of that and you get 7⅛ tablespoons, which is 4/9 cup. Working in spoons instead of cup fractions is the trick professional bakers use to scale recipes without special equipment.
